Part Number: ISO5451 My application is single pulse for few mS, I think the desat function might not be able to use, could you please let me know the control signal timing for the inside MOSFET connected to DESAT pin?
Thanks,

Part Number: ISO5852S ISO5451 ISO5452 ISO5851 Other Parts Discussed in Thread: ISO5451 , ISO5452 , ISO5851
What are the differences between ISO5851, ISO5852S, ISO5451, and ISO5452?
For what applications do the different features matter?
Audrey,
To provide an update: - A new Controller Board and new Power Board was used. The Controller Board had new ISO5451 gate drivers. - I then replaced the ISO5451 with a new ISO5851 only on the problematic gate driver on one of the Controller Boards…
Part Number: ISO5451 Hi Team,
I have a need for a desat circuit when the collector of the IGBT is tied to a 3kV supply. The circuit is using 3x 1200V diodes in series, 1kOhm from the HV bus to DESAT pin. Also, the DESAT pin has a 12V TVS diode and a…
Part Number: ISO5451-Q1 Hi
What are the failure modes and failure rates of ISO5451-Q1 when the isolation caps are broken? Short or Open? If it is short, how to guarantee the safety of the system? Thanks.
Part Number: ISO5451 Hello,
We are using the TI ISO5451 in an existing gate Driver circuit.
For driving SiC-semiconductors, we would like to add the recommended external current buffer circuit of the datasheet (pic below) to get more peak output current…
Part Number: ISO5451-Q1 Other Parts Discussed in Thread: ISO5451 Hi All ,
I have used ISO5451 for HEV Motor driver project ,but I have some questions about the use of this chip, for the PINs IN-、IN+,both has Internal pull-up resistor. whether it's not…
Part Number: ISO5451-Q1 Hello,
According to internal simplified schematic of iso5451-q1, if reset signal is in low for longer time, the output will be disabled.
Is it possible to use reset pin not only for reset but also for disable?
Thank you, TI cus…
Part Number: ISO5452 Other Parts Discussed in Thread: ISO5451 , ISO5852S Hi,
We wanted to implement an isolated IGBT driver with miller clamp to reduce turn-on of IGBT due to Ccg triggering. I was going through the datasheets of ISO5451, ISO5452, ISO 5852S…
